Calculate the LCM of 685,685,873,429

Given numbers are 685,685,873,429

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 685,685,873,429 is 85514715.

Find LCM of 685,685,873,429 with Prime Factorization


3 685, 685, 873, 429
5 685, 685, 291, 143
137 137, 137, 291, 143
1, 1, 291, 143

Multiply the prime numbers at the bottom and the left side.

3 x 5 x 137 x 1 x 1 x 291 x 143 = 85514715

Therefore, the lowest common multiple of 685,685,873,429 is 85514715.

LCM Formula to Find Lowest Common Multiple of 685,685,873,429

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

685 x 685 x 873 x 429 = 175732739325

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

685 : 1, 5, 137, 685

685 : 1, 5, 137, 685

873 : 1, 3, 9, 97, 291, 873

429 : 1, 3, 11, 13, 33, 39, 143, 429

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 685,685,873,429, is 1.

Now, the common factors can be found like this.

685:5x 137

685:5x 137

873:3x 3x 97

429:3x 11x 13

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

3x 5x 137 = 2055

Therefore, the value for common factors is 2055.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 175732739325/(1x2055)

LCM = 175732739325/2055

LCM = 85514715

Thus, we can understand that the LCM of 685,685,873,429 is 85514715.
